Kin28/Cell, a cyclin-dependent kinase, is essential for the in vivo phosphorylation of the C-terminal domain of the largest subunit of RNA polymerase II in Saccharomyces cerevisiae. In a search for mutations co-lethal with a thermosensitive kin28 mutation, we have identified genes whose products interact functionally with Kin28. In the present work, we have studied a new complementation group of synthetic lethal mutations. The corresponding gene, RIG2, encodes a predicted RING finger protein. Rig2 is likely to be a homolog of MAT1 of higher eukaryotes which forms a ternary complex with MO15(cdk7) and cyclin H. Our genetic data suggest that Rig2 is a component of transcription factor TFIIH. Transcription activity in a rig2-ts mutant is impeded at restrictive temperature. However, none of the rig2-ts mutants obtained was UV sensitive, suggesting that Rig2 is dispensable for nucleotide excision repair.
